LINE-CASTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 621,329, dated March 21, 1899. Application filed December 3, 1897. Serial No. 660,656. (No model.)

To all whom, it may concerm.

Be it known that I, HENRY JAMES DERBY- SHIRE, of Columbus, in the county of Franklin and State of Ohio, have invented a new and Improved Linotype-Casting Machine, of which the following is a full, clear, and eXact description.

The invention relates to Merg enthaler linotype-casting machines arranged to permit of casting a line or slug in proper proportions to permit of easily ejecting it from a mold, at the same time requiring no accurate cutting or trimming by the knives now employed.

The invention consists of novel features and parts and combinations of the same, as will be hereinafter more fully described, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicate corresponding parts in all the iigures.

Figure l is a face view of the mold-wheel and its mold. Fig. 2 is a cross-section of the same on the line 2 2 of Fig. l. Fig. 3 is a sectional side elevation'of the improvement with the line or slug cast and ready for ejection. Fig. 4 is a plan view ofthe same with parts in section and the line partly ejected, and Fig. 5 is a perspective view of the detached mold with the movable member removed.

In casting-machines as at present constructed it is necessary to make the line or slug tapering to allow of easily ejecting it from the mold, and smaller projections are cast on the side of the line, which may be trimmed off by the action of a knife to overcome the taper in the line, so as to make the line of an equal thickness throughout. By this operation the type is always a little smaller at the bottom than at the top, causing it to buckle in the form when being made up, and constantly topples over to `the annoyance of the compositor. By my improvement, presently to be described in detail, this is all avoided and the slug or line is cast at once in proper proportions and is ejected from the mold in a perfect condition, requiring the knives only for scraping o the little iins produced during the casting operation and caulsed by the matrices alining against the mo The mold-wheel A is mountedin the usual manner on a stud B, carried by a slide C, adapted'to be actuated from a cam-wheel D, secured on one of the shafts E of the linotypemachine, so that when the machine is in operation the mold-wheel A receives the usual intermittent motion and a reciprocating motion for moving it toward or from the knives F F, through which the line or slug G is forced after leaving a mold H, carried on the web of the casting-wheel A.

The mold H is provided with a slot H', and the outer side of said slot is preferably formed by a movable member H2, Wedge-shaped in cross section to fit the correspondinglyshaped outer portion of the slot. The member H2 is provided at its ends with lugs H3 for guiding it properly in the slot I-I and for maintaining the length and thickness of the line to be cast, as hereinafter more fully described.

To the knife F is secured a pusher I, projecting toward the face of the wheel A and in alinement with the small end of the wedgeshaped member H2 of the mold H, so that when the mold-wheel A is in the position shown in Fig. 3 and is advanced toward the knives F F then the member H2 comes in Contact with the stationary pusher I, and is thus moved partly out of the slot to release the line or slug G, which is now pushed out of the slot H by a pusher J, actuated in the usual manner from a cam J', carried by the shaft E. -Now when the Wheel A rotates for the next operation and moves into position for receiving the lead from a pot K then the pot in advancing toward the mold moves against the outwardly-extending end of the member H2, so as to push the latter back into the slot to its proper place, the small end of the member abutting against the matrices L, closing this end of the slot. (See Fig. 2.) When the parts assume this position, the cast metal can readily run from the pot K into the slot H to cast a slug or line against the matrices L, and when this has been done and the Wheel A makes a half-revolution to bring the mold to the position shown in Fig. 3 then the above-described operation is repeated-fthat is, the mold A in advancing toward the knives F F' has its movable member H2 dislodged by the pusher Ito release the cast slug IOG or line and to permit the pusher J to readily push the slug orline out of the mold over the fixed pusher I to and between the knives F F to scrape off the fins formed 'on the slug, as previously described.

It is evident from the foregoing that the knives F F require no micrometer adjustment, as is necessary in machines heretofore employed, the slug or line being at once east in proper proportions and requiring no trimming.

Vhen it is desired to change from one form of type to another, a different-sized movable member Il2 can be readily employed in the mold ll Without requiring any other changes 011 the mold.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination of the mold comprising a relatively-fixed section having a slot for the reception of the material, said slot being entirelyin the iixed section, anda member inovable in said slot in the direction of the open ends thereof and along one of the walls of the slot, the thickness of said member being less than the Width of the slot, so that a space will be left for the reception of the material between the opposite Wall of the slot to that engaged by the movable member and the exposed face of the said member.

2. The eolnbination of the mold having a through opening or slot extending" from one face of the mold to the opposite face thereof, a member movable-in said slot in the direction of the open ends of the slot, the thickness of said member being less than the Width of the slot, and an ejector arranged to move in that part of the slot which is between the exposed face of the movable member and the opposing face of the slot.

A mold having a through opening or slot With an inclined Wall, and a wedge-shaped member movable in the slot along said inclined Wall.

4. A linotype casting machine provided with a slotted mold having a movable member made Wedge-shaped, for releasing a cast slug or line.

5. A linotype-casting machine provided 5o With a slotted mold having its bottom formed by a movable Wedge-shaped member, formed at its ends with guide-lugs for maintaining the length and thickness of the line, substantially as shown and described.

6. A linotype-easting machine provided with a revolving casting-Wheel, a mold carried by the said wheel, and provided with a movable member for releasing a east slug or line, means for reciprocating the said Wheel, and a ixed pusher adapted to engage the said movable member, to dislodge it and release the cast slug or line, substantially as shown and described.

7. A linotypc-casting machine provided with a revolving casting-Wheel, a mold carried by said Wheel, and having a movable member, and a casting-pot for engaging the said member and pushing it into position in the mold, substantially as shown and described.

S. The combination of the casting-wheel mounted to rotate and also capable of axial movement, the mold carried by said Wheel, the member movable Within the mold in a di; rection approximately parallel to the axis of the wheel, the casting-pot arranged to engage one end of said movable member and to push it into the mold, and the pusher arranged to engage the other end of the movable member and to dislodge it from the mold.
